Multiple SQL injection vulnerabilities in ASPilot Pilot Cart 7.3 allow remote attackers to execute arbitrary SQL commands via the (1) article parameter to kb.asp, (2) specific parameter to cart.asp, (3) countrycode parameter to contact.asp, and the (4) srch parameter to search.asp. NOTE: the article parameter to pilot.asp is already covered by CVE-2008-2688.
ASPilot Pilot Cart 7.3 suffers from multiple SQL injection vulnerabilities, allowing remote attackers to execute arbitrary SQL commands. Successful exploitation could lead to complete compromise of the affected web application, including access to sensitive data and potentially the underlying server. This vulnerability poses a significant risk due to its ease of exploitation and potential for widespread impact.
Step 1: Identify Vulnerable Parameters: The attacker identifies the vulnerable parameters: article in kb.asp, specific in cart.asp, countrycode in contact.asp, and srch in search.asp.
Step 2: Craft Malicious Payload: The attacker crafts a SQL injection payload designed to achieve a specific goal, such as retrieving sensitive data (e.g., usernames, passwords), bypassing authentication, or writing to the file system.
Step 3: Inject Payload: The attacker injects the malicious SQL payload into the identified vulnerable parameter via a crafted HTTP request (e.g., GET or POST).
Step 4: Server-Side Execution: The web application, due to the lack of input validation, incorporates the attacker's payload directly into a SQL query.
Step 5: Database Interaction: The database server executes the modified SQL query, including the attacker's malicious code.
Step 6: Data Exfiltration/Exploitation: The attacker receives the results of the executed SQL query, which may include sensitive data or the successful execution of commands, leading to data exfiltration or further exploitation of the system.
The vulnerability stems from insufficient input validation and sanitization of user-supplied data within the ASPilot Pilot Cart 7.3 application. Specifically, the application fails to properly filter or escape special characters within parameters passed to SQL queries. This allows attackers to inject malicious SQL code through parameters like article, specific, countrycode, and srch. The injected code is then executed by the database server, enabling attackers to bypass authentication, retrieve sensitive information, modify data, or even execute arbitrary commands on the server. The root cause is a lack of parameterized queries or prepared statements, which would prevent the interpretation of user-supplied input as executable SQL code. The absence of input validation allows attackers to craft payloads that manipulate the SQL queries, leading to unauthorized access and control. The specific flaw lies in the direct concatenation of user-controlled input into SQL queries without proper escaping or sanitization.
